（1）安装nginx

0.关闭防火墙

systemctl stop firewald.service

systemctl disable firewald.service

1.使用nginx官方提供的yum源

#vi /etc/yum.repos.d/nginx.repo

[nginx]

name=nginx repo

baseurl=http://nginx.org/packages/centos/7/$basearch/

gpgcheck=0

enabled=1

2.安装和启动

yum install nginx -y

systemctl enable nginx

systemctl start nginx

（2）使用第三方扩展epel源安装php7.2

1.移除旧版的php

yum remove php-mysql-5.4 php php-fpm php-common -y

2.安装扩展源

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

3.安装php72版本

yum -y install php72w php72w-cli php72w-common php72w-devel php72wembedded php72w-gd php72w-mbstring php72w-pdo php72w-xml php72w-fpm php72w-mysqlnd  php72w-opcache

4.启动php

systemctl start php-fpm

systemctl enable php-fpm

（3）安装mysql5.7

1.安装官方yum源和下载启动mysql

rpm  -ivh  http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql57-community-release-el7-10.noarch.rpm

yum install mysql-community-server -y

systemctl start mysqld

systemctl enable mysqld

2.修改默认密码

password=$(grep "temporary password" /var/log/mysqld.log  | awk '{print $NF}')

mysqladmin -uroot -p$password password 'Redhat@123

（4）配置nginx动态请求转发至php

1.修改nginx配置文件

#vim /etc/nginx/conf.d/php.conf

server {

	server_name www.test.com;

	listen 80;

	root /webroot/www;

	index index.php index.html;

	location ~ \.php$ {

		fastcgi_pass   127.0.0.1:9000;

		fastcgi_index  index.php;

		fastcgi_param  SCRIPT_FILENAME  /webroot/www$fastcgi_script_name;

		include fastcgi_params;

			}

		}

#nginx -t

#nginx -s reload

2.添加测试页面

mkdir -pv /webroot/www

#vim /webroot/www/info.php

<?php

	phpinfo();

?>

3.验证

4.连接数据库测试

使用mysqli模块测试连接mysql

#vim /webroot/www/mysqli.php

<?php

	$servername = "localhost";

	$username = "root";

	$password = "Redhat@123";

	//注意mysql密码

	// 创建连接

	$conn = mysqli_connect($servername, $username, $password);

	// 检测连接

	if (!$conn) {

	die("Connection failed: " . mysqli_connect_error());

        }

	echo "连接成功";

?>

使用pdo模块测试连接mysql

#vim /webroot/www/pdo.php

<?php

        $servername = "localhost";

        $username = "root";

        $password = "Redhat@123";

        try {

        $conn = new PDO("mysql:host=$servername;dbname=mysql", $username, $password);

        echo "连接成功";

        }catch(PDOException $e)

        {

        echo $e->getMessage();

        }

?>
